Working principle and main performance of pressure transmitter

Working principle of pressure transmitter
The electrical component that senses pressure in a pressure transmitter is generally a resistance strain gauge, which is a sensitive device that converts the pressure on the measured object into an electrical signal. The most commonly used types of resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. 

There are two types of metal resistance strain gauges: wire strain gauges and metal foil strain gauges. Usually, strain gauges are tightly adhered to a mechanically strained substrate using a special adhesive. When the substrate undergoes stress changes, the resistance strain gauges also deform, causing a change in the resistance value of the strain gauges and a change in the voltage applied to the resistance.

Main performance of pressure transmitter
1. Widely used as the tested medium, it can measure oil, water, and paste materials compatible with 316 stainless steel and 304 stainless steel, and has a certain degree of anti-corrosion ability;
2. High accuracy, high stability, using imported original sensors, good linearity, and high temperature stability;
3. Small size, light weight, easy installation, debugging, and use;
4. Stainless steel fully enclosed shell, with good waterproofing;
5. The pressure sensor directly senses the pressure of the measured liquid level, without being affected by the foaming or deposition of the medium.
